To (LIZ u-iom. it may concern.:

Be it known that` I, GEORGiE ANNANCAR- PENTER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New Specification of Letters Patent.

York, administratrix of the estate of HIRAM i HENRY CARPENTER, deceased, iate a citizen of the United States, andi late a resident of the city of New York, borough oftianliattain in the county and State of New York, as by reference to the duly certified copy of letters of administration hereto annexed will more and who did in his lifetime ni age. Batteries, do hereby declare the following to be a full, clear, and exact description of said invention.

The invention consists in the form, ar-

parts use( in a storage battery, whereby certain advantages are attained as hereinafter described.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in ali the figures.

Figure 1 is a. perspective view showing the positive-and negative grids of a storage. battery cell as removed from thev containing v issel but otherwise assembled and ready ir use', Fig. 2 is a horizontal section through the saine, taken upon a plane s upper-surface of the grids; Fig. Itis a frfoe inentary section through one fori :fifa tive plate fand Fig. 4 is a fragmentary section through another form (if negative plate.

The negative pole. electrodes are shown at 5,' 6, and are arranged in p'aiis as indicated in Fig. 2, the plates of cach,I pair being separated by a rod 7 of hard rubber, vulcanite, or other insulating material. A

Where the foi-in indicated .in Figs. 1, 2 and 3 is used, the electrode is' provided with )erforations 7 'a audits-also provided with a iiliing 8 having holes 9 therethrough, these holes being in exact registry with the holes 7a as indicated in Fig. 3.

In the form shown in Fig. 4 the electrode iilled With active material 8 having perforations or holes 9' registering with the perforatioiis 7 a. In this case a central, sheet of metal 9b' corresponding in substance. to the ight ly above the.

saine and through the. active material 8a.

The terminals of the electrodes 5, 6, and Sai are shown at 10, 10a, and secured together and provided with a binding post l1 as indicated in Fig. 1. are shown at 12 and are of double the Width of the negative pole electrodes 5 and 6 as Will be understood from Fig. 2. Each positive ole electrode 12 is perforated as shown and is filled with active material 13. The preferred active material is cerussite, but any other active material may be employed. The several positive plates are connected together by strips 14, the latter being provided with a binding post 15. A number of comparatively thin bars 16 of insulating material, preferably rubber, are used to space the electrodes a )art as indicated lin Fig. 2. A nuii'ii" ir of i'esillient bands 17 areplaccd around thi plates so as toA hold the saine firmly together. When the several plates are assembled as indicated in Fig'. 2, tl'iere are passages 18 intermediate of the electrodes, and through these passages the exciting liquid is free to circulate.

Thisgitinvention is in part based upon the discovcrythat if the. negative pole electrodes be nia'de of comparatively small size and double in number they afford certain ad. an- Among these advantages are the following: l. The plates of both kindsmay be. 'lorined with greater rapidity; 2. The of the cell is diminished;

.hours is increased; and 4. The charging and discharging of the cell may be regulated t greater advantage by changing the relative aggroupmcnt; and 5. .The aniperage of the battery is doubled.

W' ith a battery thus constructed the negative pole electrodes at one end of the cell, for instance, those at the ri ht of Fig. 2, may be connected up with t e positive Positive pole electrodes ole electrodes by merely treating the middle binding screw l5 and the right hand binding screw 11 as theterminals of the battery. When the negative vpole right are thus exhausted the negative conriection maybe shiftedover to the other negative binding post. 11 and la dischar e renewed until .the restv of the negative po e electrodes are exhausted. If desired, the tivo 1binding-posts 11 maybe both connected to' electrodes at the ics the same Wire, constituting one terminal ot `the system to be operated upon, the binding post being connected to the opposite LTative plate. Each negative pole electrode and its contents also constitute a plate. The

arrangement also increases the duration of the battery if the negative pole electrodes are 15 not all disch arged, at once. "'rhile the draW- ing shows only two negative electrodes for each positive electrode this arrangementis not to be regarded a limitation.

The invention is not limited to the use of flat easings or envelope as electrodes. The casings or envelops may be of various snapes and proportions.

I Having thus described my invention, l claim as new and desire. to secure by ,Letters Patent- 1. In a storage battery, the combination of a plurality of negative plates arranged in airs, the individual plates ot each pair beinpr insulated from each other, connections for 3f) joining together one plate ol" each pair, sepa rate connections for joiningr together the other late of each pair, a. plurality olE positive p ates sandwiched intermediate oi' said negative plates, one positive plate having a surface substantially equal to that ot one pair of said negative plates, and connections l'or joiningr together said positive plates.

2. ln a storage battery, the combination of a plurality of negative plates arranged edile 40 to edge 1n pairs, connections lor joiningr together one plate of each pair, means 'lor insiilating from each other the plates ol eaeh pairlv separate connections lor joining iogethcr the several other plates olieaeh pair, a plurality of positive plates sandwiched inlermediate of successive pairs ol said 'negative plates, spacingr rods ol` inrmlating material dis )osed intermediate oll said positivo plates and said negative plates, connections tor joining together said positive ilates. and rub-- ber bands encircling both said posit ivo plates and said negative plates andA holding thev same iirinly together.

y 3. ln a. storage battery, the combination of a plurality oi plates of one sign a ranged in 5 Jans, the individual platesol each pair i, insulated trein each other, connections ler joining together one plate of each pairseparate connections 'for joining together the other plate ol each pair, and a plnral'ty ot' 6e plates ot a different sign connected together and sandwiched intermediate et said first mentioned plates7 said plates of said different sign each having a surface substantially equal to that oione pair of said first-nien tioned plates.

4. ln secoinlary battery, a cell comprising a plate of one sign, and a plural' y of plates 'ot the opposite sign, the aggregate or the areas ol the pluralityof plates being sul 'f o Vstantially equal to the areas oi the rslnientioned plate.

5. ln a secondary battery, a plate of one' sign, plurality ot plates of the opposl' l the aggregate o'l. the area'oi the p-iuraiit plates being su"ostantiallyT equal to the area oi' the single plate, means to connect the plurality ot plates, and means to insulate the plates one 'from the other.
